To solve the assertion-reason question, we will analyze both the assertion (A) and the reason (R) step by step. ### Step 1: Understand the Assertion (A) The assertion states that the significant figures for 0.200 is 3, whereas for 200 it is 1. - **Analysis of 0.200**: - The number 0.200 has three significant figures: the digits '2' and '0' after the decimal point are significant because they indicate the precision of the measurement. - Therefore, 0.200 has three significant figures (2, 0, 0). ...
